Book Description
Significant progress has been made in the research into the molecular basis of vision, especially retinal proteins, which are the components of visual reception. The results of these studies open wide prospects for their application in medicine and in the construction of unique light-sensitive materials for holography and microelectronics. Therefore, research into retinal proteins is not only important for understanding the mechanisms of the native light-transducing systems but also for the development of new technologies. An international group of scientists discussed the key aspects of the study of light-sensitive systems at the Conference on Retinal Proteins held in July 1986. This Proceedings volume contains 45 papers that were presented on this important topic in molecular biology.

Book Description
The main purpose of this volume is to provide a focused analysis of the function of the G protein-coupled signaling pathways that operate in the interconnected network of retinal neurons as they detect and encode the information carried by light. The organization of this volume will generally follow the path of signal flow in the retina. First we will describe recent advances in understanding the phototransduction cascade of rod and cone photoreceptors, which use signaling cascade based on the GPCR rhodopsin to transduce incident light into neural activity. Chapters will be devoted to unique specializations of the two major types of photosensitive cells that comprise the predominant input for our spatial and color vision. Subsequently, the mechanisms of synaptic information encoding by retinal ON bipolar cells will be described, where the GPCR mGluR6 plays a fundamental role. Chapters in this section will examine macromolecular organization of the mGluR6 signaling pathway as well as current understanding of its function. The functional characteristics of this signaling mechanism will be explored in detail. Additionally, this section will cover the role of dopamine receptors in modulating signal transmission between photoreceptors and ON-bipolar cells. Finally, chapters will be focused on the output neurons of the inner retina, ganglion cells, where the components of the emerging GPCR melanopsin cascade in intrinsically photosensitive ganglion cells will be detailed. Collectively these mechanisms allow the retina to represent visual space over a wide range of light intensities.

Over 2095 illustrations *1800 in full color* from the authors' collections represent one of the finest compilations of rare and unusual ocular conditions available. Comprehensive, yet concise, it explores new topics such as complications of corneal surgery, vascular disorders, secondary cataracts, bone-marrow transplant retinopathy, neural retinal detachment, ocular melanotic tumors, and more. Plus, a companion CD-ROM and text/CD-ROM package are available! Explores new topics such as complications of corneal surgery, vascular disorders, secondary cataracts, bone-marrow transplant retinopathy, neural retinal detachment, and ocular melanotic tumors (including diabetes). Offers expanded coverage of entities such as chromosome 17 deletion syndrome, necrobiotic xanthogranuloma, climatic protoglycan stromal keratopathy, unilateral acute idiopathic maculopathy, acute mutifocal retinitis, idiopathic polypoidal choroidal vasculopathy, North Carolina macular dystrophy, familial internal limiting membrane dystrophy, clumped pigmentary retinal dystrophy (clumped pigmentary retinal degeneration), vasoproliferative retinal tumors, Schwartz's syndrome, familial amyloidotic polyneuropathy, familial atypical mole and melanoma (FAM-M) syndrome, and more! Features specific genetic profiles for many existing entities.

Book Description
This book deals with the cellular biology, biochemistry and physiology of photoreceptors and their interactions with the second-order neurons, bipolar and horizontal cells. The focus is upon the contributions made by these neurons to vision. Thus the basic neurobiology of the outer retina is related to the visual process, and visual defects that could arise from abnormalities in this part of the retina are highlighted in the first 16 chapters. Since all vertebrate retinas have the same basic structure and physiological plan, examples are given from a variety of species, with an emphasis upon mammals, extending to human vision. The last four chapters approach the problem from the other end. This part of the book covers a range of clinical conditions involving visual abnormalities that are due to cellular defects in the outer retina. Although the contents of this book do not represent the proceedings of a conference, the concept arose at an international symposium on 'Recent Advances in Retinal Research' which was held at the International Marine Centre in Oristano, Sardinia. We hope that the book will give a coherent, up to date review of the neurobiology and clinical aspects of the outer retina and encourage further integration of these areas. Retinal neurobiology has been an intense field of investigation for several decades. More recently, it has seen significant advances with the application of modern techniques of cell and molecular biology.

Book Description
Since 1984, we have organized Satellite Symposia on Retinal Degenerations that are held in conjunction with the biennial International Congress of Eye Research. The timing and location of our Retinal Degeneration Symposia have all owed scientists and clinicians from around the world to convene and present their exciting new findings. The symposia have been arranged to allow ample time for discussions and one-on-one interactions in a relaxed atmos phere, where international friendships and collaborations could be established. The II International Symposium (also known as the Sendai Symposium on Retinal Degeneration) was held in 1986 in Sendai, Japan, on the occasion of the retirement of Kat suyoshi Mizuno as Professor and Chairman of Ophthalmology at Tohoku Medical SchooL On October 5-9, 1996, we returned to Sendai, where the VII International Symposium was held at the Miyagi Zao resort hotel in the beautiful Mt. Zao region of northern Japan. This meeting was held on the occasion of the tenth anniversary of Makoto Tarnai as Pro fessor and Chairman of Ophthalmology at Tohoku Medical School. One afternoon of the meeting contained a special symposium in honor of Professor Tarnai, who has signifi cantly elevated the level and intensity of research on retinal degenerations at his university and in Japan during this past decade.

Book Description
This book, now in a thoroughly revised second edition, offers a comprehensive review of the rapidly growing field of optogenetics, in which light-sensing proteins are genetically engineered into cells in order to acquire information on cellular physiology in optical form or to enable control of specific network in the brain upon activation by light. Light-sensing proteins of various living organisms are now available to be exogenously expressed in neurons and other target cells both in vivo and in vitro. Cellular functions can thus be manipulated or probed by light. The new edition documents fully the extensive progress since publication of the first edition to provide an up-to-date overview of the physical, chemical, and biological properties of light-sensing proteins and their application in biological systems, particularly in neuroscience but also in medicine and the optical sciences. Underlying principles are explained and detailed information provided on a wide range of optogenetic tools for the observation and control of cellular signaling and physiology, gene targeting technologies, and optical methods for biological applications. In presenting the current status of optogenetics and emerging directions, this milestone publication will be a “must read” for all involved in research in any way related to optogenetics.
